Please anyone, i need help!! I`m confusion! Anil completes the 72km journey between Cardiff and Bristol in 48 minutes.

He then drives 69km from Cardiff to Swansea at an average speed of 60km/h

Work out Anil`s average speed (in km/h) for his total journey from Bristol to Swansea.

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
